OPP aluminum plated filmIt is a composite material that uses polypropylene (OPP) film as the substrate and is coated with a layer of aluminum film on its surface. This film not only has the good characteristics of polypropylene film, such as tear resistance, rigidity, moisture resistance, chemical resistance, etc., but also has the excellent properties of aluminum film, such as high gloss, oxygen barrier, moisture barrier, and light shielding.
1、 Manufacturing process of OPP aluminum plated film
The manufacturing process of OPP aluminum plated film mainly includes the following steps:
1. Preparation of OPP film: Heat polypropylene particles to a molten state and extrude them into OPP film.
2. Preparation of Aluminum Coating: Using
vacuum coating technologyHeat the aluminum sheet to a molten state and perform semiconductor deposition of the aluminum film on the surface of the OPP film to form a thin aluminum film layer.
3. Treatment of aluminum plated film: OPP aluminum plated film is produced by subsequent processes such as calendering, cutting, and winding of the aluminum plated film.
2、 Characteristics of OPP aluminum plated film
1. High glossiness: The surface of the aluminum plated film has high brightness and luster, so OPP aluminum plated film has high glossiness, making the appearance of the product more dazzling.
2. Oxygen and moisture insulation: Aluminum film is mainly used for oxygen and moisture insulation, because OPP aluminum plated film has this excellent characteristic, it can effectively protect the freshness and quality of the contents inside the packaging.
3. Chemical resistance: OPP aluminum plated film has excellent chemical stability and can resist corrosion from chemicals such as acid and alkali.
4. UV protection: OPP aluminum plated film can block the invasion of ultraviolet rays, effectively extending the shelf life and service life of the product.
5. Temperature resistance: OPP aluminum plated film has good temperature resistance and can maintain the stability of its physical properties within a certain temperature range.
6. Good adhesion:
OPP aluminum plated filmHas good adhesion and can effectively bond with other materials, with strong adhesion.
3、 Application of OPP Aluminum Coating
OPP aluminum plated film is widely used in packaging materials for industries such as food, medicine, cosmetics, and printing. Specifically, it includes the following aspects:
1. Food packaging: OPP aluminum plated film is widely used in food packaging, such as beverages, alcoholic beverages, etc., which can effectively protect the quality and freshness of food, improve the grade and appearance of products.
2. Pharmaceutical packaging: The pharmaceutical industry has very high requirements for packaging materials. OPP aluminum plated film not only has good moisture resistance and sealing performance, but also effectively blocks ultraviolet rays, improving product stability and effectiveness.
3. Cosmetics packaging: Cosmetics packaging requires higher appearance, and the high glossiness and brightness of OPP aluminum film make the product more textured and improve its sales ability.
4. Printing industry: OPP aluminum plated film can be used as a printing material to give printed products high glossiness and make the colors of printed products more vivid and rich.
4、 Summary
OPP aluminum plated film is a composite material with excellent properties, mainly characterized by high glossiness, oxygen barrier, moisture barrier, chemical resistance, etc.
OPP aluminum plated filmWidely applicable, it is widely used in packaging materials for industries such as food, medicine, cosmetics, etc. It can also be used as a printing material to improve the color brightness and texture of printed materials.
